Raspberry plant named ‘Driscoll Carmelina’

ABSTRACT

The present invention relates to a new and distinct cultivar of raspberry plant named Driscoll Carmelina. The new cultivar is distinguished from other raspberry cultivars by its late primocane production, high spring yields, good flavor and disease resistance. The new cultivar is distinguished from its seed parent by having better release from the receptacle, firmer fruit and better spring bud break. The new cultivar is distinguished from its pollen parent by producing firmer fruit with better shipping characteristics.

Latin name of the genus and species of the plant claimed: The variety isbotanically identified as Rubus idaeus L.

1. BACKGROUND OF THE INVENTION

The new cultivar of raspberry plant was developed from the hybridizationof the selection ‘P362.1’ (an unpatented variety) as the seed parentwith the selection ‘N119.1’ (an unpatented variety) as the pollenparent. The parents were crossed in 1995, whereafter fruit and seed werecollected to produce seedlings for field planting in Watsonville, Calif.in 1995. The new cultivar was selected from these seedlings in 1997 forits large size, good flavor, and productivity. The new cultivar has beenasexually propagated by in vitro shoot tip culture, root sucker divisionand root cuttings at the Cassin Ranch in Santa Cruz county, Calif. andhas been shown to maintain the desired and distinguishingcharacteristics after propagation over several generations.

Latin name of the genus and species of the plant claimed: The variety isbotanically identified as Rubus idaeus L.

2. SUMMARY OF THE INVENTION

The present invention provides a new and distinct cultivar of redraspberry plant named ‘Driscoll Carmelina’. The cultivar is botanicallyidentified as Rubus idaeus L. The ‘Driscoll Carmelina’ red raspberryplant produces a primocane crop which begins in late July and continuesuntil early November. The floricane crop begins in late May andcontinues until mid-July. Floricane yields are high relative to othercomparable varieties. The fruit of ‘Driscoll Carmelina’ has consistentlygood flavor and the fruit separates easily from its receptacle.

4. DETAILED BOTANICAL DESCRIPTION

The following detailed description of the new raspberry cultivar,‘Driscoll Carmelina’, is based upon observations taken of 7 to 17 monthold plants and fruit grown in Watsonville, Calif. between 2001 and 2002,and is believed to apply to plants of the ‘Driscoll Carmelina’ cultivargrown in similar conditions of soil and climate elsewhere.

Throughout this specification, color names beginning with a small lettersignify that the name of the color, as used in common speech, is aptlydescriptive. Color data followed by an alphnumeric code indicates themost similar color designations as provided by The Royal HorticulturalSociety (R.H.S.) Colour Chart published by The Royal HorticulturalSociety of London, England. Color designations, color descriptions, andother phenotypical descriptions may deviate from the stated values anddescriptions depending upon variation in environmental, seasonal,climatic and cultural conditions.

Table 1 provides information on the plant and fruit characteristics ofthe new cultivar ‘Driscoll Carmelina’ compared with characteristics ofthe unpatented raspberry cultivar ‘Heritage’. Observations of thecultivars were taken under similar conditions.

The new variety is particularly characterized and distinguished fromother cultivars by its late primocane production, high spring yields,good flavor and disease resistance.

The fruit color of ‘Driscoll Carmelina’ is a deep red at harvest. Fruitof ‘Driscoll Carmelina’ separates easily from the receptacle and is ofgood firmness at harvest. The fruit of ‘Driscoll Carmelina’ is veryconsistent in size and shape throughout the harvest period. There werean average of 17 young shoots in the observed plants of ‘DriscollCarmelina’ and the shoots emerged around February 22nd. The pigmentationcolor of both surfaces of the petals is 155D and there are five petalsper flower. The color of the seeds of ‘Driscoll Carmelina’ is 161A, theaverage seed weight is about 1.4 mg, and there are an average of about91 seeds per fruit.

The floricane yields of ‘Driscoll Carmelina’ are high relative to thevariety ‘Heritage’.

‘Driscoll Carmelina’ is distinguishable from its pollen parent,selection ‘N119.1’, by producing firmer fruit with better shippingcharacteristics. The new cultivar is distinguished from its seed parent,selection ‘P362.1’, by having better release from the receptacle, firmerfruit and better spring bud break.

4.1. DISEASE AND STRESS RESISTANCE

The cultivar has good tolerance to late leaf rust. Resistance to rootrots is intermediate to other varieties. Cold tolerance of the newcultivar has not been established. Post harvest fruit rot resistance isgood in comparison over many selections and varieties.

4.2. NUCLEIC ACID FINGERPRINTING

Distinctive patterns of polymorphism can be detected using a variety ofnucleic acid analysis methods. In one non-limiting example, moleculargenetic maps can be produced using random amplified polymorphic DNA(RAPD) (Williams et al., 1990, “DNA polymorphisms amplified by arbitraryprimers are useful as genetic markers”, Nucleic Acids Res.18(22):6531-5). Using a variety of oligonucleotide primers, alone or incombination, RAPD analysis of Driscoll Carmelina and Heritage yieldedDNA fragment patterns that uniquely distinguish each of thsesgenetically distinct genotypes.

We claim:
 1. A new and distinctive cultivar of raspberry plant,substantially as shown and described.
